Getting to know all kinds of optical fiber patch cord


LC  Patch : The LC patch cuts off with the LC connector. LC stands for Lucent connector. LC connector is a structure of pressure and fastening type. This type has a plastic body and ferrule with a precise size 1.25mm and ceramic. The LC type light patch is a popular type of light patch cord that reduces space occupancy, and is widely used to install and operate densely populated areas. The LC patch uses a 1.25 mm ferrule, which is about half the ST patch. This Patch Cord has a very good performance in the single-shot mode, and is of interest to most people and has high usage. Patch Cord LC complies with IEC and Telcordia, ANSI / EIA / TIA standards. The Patch Cord LC connector is also used for a size of 1.6mm / 2.0mm and also for a 3.0mm size.


Patch Cord SC:  Cordy patch ends with SC connector. The SC connector was invented by the Japanese company NTT. SC stands for a common connector or square connector or standard connector. Their use in fiber optic data and communication communications is very common. This type of connector is of a type of pressure and elasticity and can be used for 1000 cycles of connection. The SCC is locked in its connector and, through this ceramic ferrule, creates a precise, precise connection. Patch Cord is a low-cost, simple, and durable SC, which is a feature of this connector. This type is cheap and economical. The SCC patch is widely used in fiber optic networks and can be combined with zirconium oxide and plastic frame.


Patch Cord ST: Patch Cord ST Optical fiber optic connector with ST connector. ST stands for Straight-Tip and is as follows. The diameter of the ST connector is like a 2.5 mm SC-connector SC. This kind of patch is developed by AT & T and has been very popular in the 1980s and 1990s. The ST connector is bayonet shaped and has a long spring spring to hold the fiber. This type of patch is available in both multi-mode and single-mode modes. The horizontal and horizontal duplex adapters are fitted with metal or plastic enclosures, and can be divided into two types: bronze phosphate or zirconium oxide liners. Of course, people may be more interested in metal than in a plastic case. The ST-Patch Cord has a straight and straight tip that makes it easy to get in and out. If you feel that you have a high power dissipation, you can re-fit it. This type of connector continues to work up to 500 times the standard entry and exit without any problems. The ST-Fiber Patch Cord is a patch cord of older generations, but is still widely used for multimodem networks, including local networks for buildings and universities.


FC Patch Cord: FC  Fiber Patch Cord has a FC connector and it’s tricky to connect. FC stands for Fixed Connector. Like the SC connector, FC was also invented by NTT. The FC Patch Cord has a metal body and torsional structure. In the Patch Cord, FC ferrules and liners are used in connectors like the SC connector. FC Patch Cd is available in both single-mode and multiplayer mode. This type of patch cord can be used in high vibration environments and tightly closed, but it is necessary to insert it in a correct and level before tightening the patch.


Patch Cord MTRJ: The MTRJ  Patch Cord is completed with the MT-RJ Connector. MT-RJ stands for Mechanical Transfer Registered Jack. The MTRJ connector is developed by MT and RJ connectors. This kind of patch cord has a chamber and a plastic ferrule, which is a special feature of the connection of two fiber optic connections. The MTRJ connector has been adapted using the Ferrule MT form produced by NTT. Each MTRJ connector has two dual-fiber chips (duplex) and is similar to the RJ45 Ethernet copper connector. Its size is half as large as the SC connector, and in fiber-to-desktop solutions, it can lead to lower prices on any fiber port. MTRJ connectors are available in two ways (with two metal pins) and (without needles and pins). The MTRJ patch is commonly used for network applications. Its size is slightly smaller than the standard phone jack and is easy to handle.


E2000 Patch Cord: The E2000  Patch Cord is closed with the E2000 Connector. The E2000 connector is designed to protect the ferrule from dust and scratches, with a spring-shaped valve and diaphragm. The valve and diaphragm of the connector are automatically closed when the free connector is closed. This spring-shaped valve causes the contamination to not enter or the laser light does not come out of the connector. When the adapter is connected, the valve opens automatically. With the same structure as the SC connector, the E2000 connector is smaller. The E2000 Patch Cord is one of the latest styles and designs of this type of cable, yet it is one of the most expensive fiber optic patches.


Patch Cord MU: The MU  patch cassette with MU connector is terminated. The MU connector is also the invention of NTT. It has a cover and a plastic compartment, and its structure is Push & Pull. The MU connector is a small form factor connector that features a ferrule LC connector with a diameter of 1.25mm. The MU connector has the same locking mechanism as the SC connector, which is based on pressure and elasticity. Optical MU connector is similar to LC and sometimes called a small SC. MU connectors are used in advanced optical transmission, interchange, and shared systems or high data processing software. Recently, the MU Patch Cord has been developed to be used in the future for SC.


Patch Cord MPO / MTP: The MPO patch cord has been terminated with the MPO connector. The MPO Patch Cord is a high-capacity patch cord coupled with a fiber-optic connection to the MT-type ferrule. This is a tester-based connector that is compatible with IEC 61754-7 and TIA / EIA 604-5A, and is highly cost-effective for end-of-pipe and demolition purposes and for high-capacity applications. This kind of patch cord is usually used in the ribbon type cable and is used in multi-fiber output box assembly. The MPO includes a few fiber in each connector, which means that the MPO can establish multiple connections with one connector, which can be 12, 24, 36 and more. MTP is an upgraded version of the MPO. The MTP connector creates a high capacity connection between the network equipment in the telecommunication chamber and is suitable for these applications. This type of patch clasp is based on the push and pull system, it can be easily inserted and removed.


Optical fiber patch cabinets with different types of optical cable

The patch cord can be divided into various parameters of the fiber optic cable. According to the consumables for cables, all types of PVC, Riser Plenum, OFNR, OFNP, LSZH and … are divided. The number of chords used is divided into two types: simplex and duplex. Simples use a fiber-optic chunk of two fiber optic chords. According to the type of choreographer used, the patch is divided into two types of multi-mode and single-mode modes. The single-patch cord is generally yellow with a fiber size of 9 / 125μm, while the orthogonal multicomponent with a fiber chord size of 62.5 / 125μm. Additionally, the Patch Cord Multum has a different division, which is grouped into two types of OM3 and OM4.
